SPECIFICATION forming part of Letters Patent No. 752,042, dated February16, 1904.

Application filed August 20, 1903.

T at whom it may concern:

Be it known that I. DOMINIGK CORADINO, a citizen of the United States,and a resident of Jersey City, county of Hudson, State of New 'Jersey,have invented certain new and useful which Figure 1 is a front view ofthe improved burner with its attachments; Fig. 2, a top plan of theburner alone; and Fig. 3 a horizontal cross-section on line 3 3 of Fig.1.

In carrying out my invention as illustrated by the drawings I employ anannular chamber A, which is formed by an outer tube or wick-tube Band aninner tube or draft-tribe C. This draft-tube C is open at the bottom andis connected by two spiders D D "with a centrally-located tubular guideE, open at the top and either open or closed at the bottom, as may bedesired.

The annular chamber A is connected with an oil-supply in any suitablemannerfor instance, by a pipe F. In the upper portion of the chamberA isarranged the oil-feed band, which takes the place of a wick. This bandis adapted to be moved up and down by means of any suitable mechanism.

A spindle H carries at its upper end a cap I, adapted to extendoutwardly over the oilfeed band. The cap I may be ad justably securedupon spindle H in any suitable manner,

' which will not be affected, however, by the heating of the cap-as, forinstance, by the thread and nut constructionsho'wn.

Below the cap I a spider J is secured to the spindle H in any suitablemanner, the preferable construction, however, being to provide a threadwithin the said spider and screw it tightly down to the end of thethread on spindle H, said thread extending the proper distance. Upon theperiphery of spider J a deflector-ring L is-secured, which deflector--ringL is. provided at its upper end with a of said spindle.

tends below the spider J .which lower portion of said spindle is adaptedto fit loosely into the central guide-tube E, but not loosely enough topermit of appreciable lateral play The spindle H is inserted into thecentral guide-tube E untilthe hub of spider J rests and is supportedupon the upper end of said central guide-tube E, when the cap I and thedeflector-ring L will be held in operative positionment relatively tothe wick and draft tubes and the feed-band as well as to the outsidedraft-deflector G, which forms a portion of the general construction ofthe burner.

It will be seen that the spindle H and the parts mounted thereon may belifted up and out of the central guide-tube E, and this feature is verydesirable, both for the reason that it enables the spreader, as. I termthe entire piece comprising the spindle H and parts carried thereby, tobe easily removed and for the reason that when the oil-feed band israised too high, as is often the case, it permits cap I to risetherewith, preventingthe crushing of the upper end of said oil-feed bandby the said cap if said cap were fixed instead of movable.

Another prominent and very useful feature of this construction is thepermitting of the spreader to resume its normal position by gravitywhen'the oil-feed band is again lowcred, which is attained by providingthe fit of the spindle H in the central guide-tube loose enough toinvariably attain this result by the weight of the'spreader.

A desirable construction of the spreader is illustrated in Fig. 1, thespider J being fixed upon the spindle H, a section of tube K fitted overthe spindle H and resting on the hub of the spider J determining thedistance between said spider and the cap I, the cap I apcrtured andthreaded to screw on the spindle H to rest upon the tube-section K, anda nut M screwed down on said threaded portion of the spindle against andto retain cap I.

It will be seen that the spider J being screwed down. tight against theend of the thread on spindle H always. holds the deflector-ring L in thesame relative position to spindle H and that the cap I is threaded uponspindle H, and therefore adjustable to vary 55 tube, a feed-bandimmediately without said the distance between the said deflector-ring Land the cap I. The lock-nut M will fix the cap at any point upon thespindle H to which it may be adjusted; but I provide 'the tubesection Kto determine this distance, and it may be filed oil or a washer added tovary its length. Any means may be employed to regulatethe distancebetween the deflector-ring and the cap without departing from the spiritof my invention.

The cap I is provided with a series of apertures N about its centralportion adjacent to the spindle H.

It will be observed that air is supplied to the flame at four differentpoints. First, a certain amount of air passes up between the outsidedraftdeflector O and the wick-tube B: second, an annular film of airpasses through the spiders and between the draft-tube C and thedeflector-ring L and reaches the inner edge of the oil-feed band; third,a further supply of air passes through the spiders up through thedeflector ring L and after being first thrown inward is deflectedoutward by the cap I, so as to cause the flame to flare outward;finally, there is also a central draft through the spiders and theapertures N in the cap I. By all these means a very complete combustionis insured and the flame given shape suitablefor heating purposes by avery simplyconstructed and eflicient device.

By providing the apertures N in the cap I, I utilize the sameconduitnamely, the channel through the spidersfor the central draft asis provided for the bulk of the drafts and may vary the volume of saidcentral draft simply by varying the size of the apertures N, the saidcommon conduit being capable of supplying ample draft.

Another feature of my present invention is the constructing of thecentral guide-tube E with two spiders some distance apart, which spidersmay be made to fit snugly in the wick tube B, but yet be adjustablelongitudinally therein or removable therefrom, which. con struction atthe same time always insures the perfect centering of the deflector-ringL and cap I.

- It is'obvious that various changes may be made in the details ofposit-ionment and construction without departing from the spirit of myinvention.

What I claim as new, and desire to secure by Letters Patent, is

1. In a burner, the combination of a draftdraft-tube, a guide-tubemounted concentricallywith said draft-tube, the outside diameter of saidguide-tube being of a lesser diameter than the inner diameter of saiddrafttube, thus forming an annular chamber about said guide-tube, and adeflector-rin g mounted upon a spider having a central spindle adaptedto fit loosely in said guide-tube, said deflectorring dividing the upperportion of said anspider frictionally engaging the inner walls of saiddraft-tube thus forming an annularchamber about said guide-tube, aspindle adapted to it loosely in said guide-tube, a

deflector-ring of lesser, diameter than said draft-tube and greaterdiameter than said guide-tube inotiinted concentrically upon saidspindle by means of a spider, fast upon said spindle, and a cap ofgreater diameter than said feed-band concentrically mounted on saidspindle above said deflector-ring to project over said feed-band, saidcap provided with apertures about its central portion afibrdingcommunication between said annular'chamber to the space above said cap,said spindle adapted to be lifted 'bythe raising of said feed-band andto gravitate to its normal position when said feed-band is againlowered.

3.- In a burner, a spreader comprising a spindle, a spider mounted uponsaid spindle, a deflector-ring mounted upon the periphery of saidspider, a section of tubing fitting over said spindle and resting onsaid spider, a cap having a central aperture fitting on said spindle andresting on said section of tubing,- said cap providediwith a series ofapertures arranged about its central aperture, and a nut threaded uponsaid spindle and retaining said cap and section of tubing thereon.

4:. In a burner, a spreader comprising a spindle, a deflector-ringmounted upon said spindle, a cap mounted on said spindle, one of saidelements adjustably mounted upon said spindle to permit of the varyingof the distance between them.

5. In a burner, a spreader comprising a spindle threaded throughout aportion of its length, a deflector-ring having a spider-support threadedand screwed down against the end of said thread upon said spindle, a capthreaded on said spindle and a lock-nut for,

fixing the position of said cap on said spindle.

6. In a burner, a spreader comprising a spindle threaded throughout aportion of its length, a deflector-ring having a spider-sapport threadedand screwed down against the end of said thread upon said spindle, a capthreaded on said spindle, a section of tube about said spindledetermining the distance between said deflector-ring and said cap, and alock-nut for fixing the position of said cap when screwed into place.

In testimony whereof I have signed my name to this specification 1n thepresence 01' two subscribing witnesses.
